Police in Washington D.C. arrested a Texas woman who allegedly traveled to Washington D.C. with a loaded firearm and made threats against former President Donald Trump.

The woman, Christina Montoya, was arrested after traveling to the nation’s capital. Law enforcement was first alerted to her threats by the Secret Service, according to a statement from the D.C. Metropolitan Police.

“Through the detectives’ investigation, 41-year-old Christina Montoya of San Antonio, Texas, was arrested and charged with carrying a pistol without a license, possession of an unregistered firearm, and threats against a former president,” police said in a statement.

Investigators said threats against the former president started on July 20. Police were able to locate the woman’s vehicle and found a Smith & Wesson M&P Shield pistol, a magazine and a gun lock after conducting a search, according to the police report.

The incident comes just weeks after Trump came millimeters away from assassination during a rally in Butler, Pennsylvania.

In the weeks following the shooting, the Secret Service has been under intense scrutiny due to apparent security failures before and during the Pennsylvania rally. The Secret Service was aware of would-be Trump assassin Thomas Matthew Crooks at least 90 minutes before the shooting, though the rooftop from which he fired was ultimately left uncovered.

Former Secret Service Director Kimberly Cheatle ultimately resigned after several Republican and Democrat lawmakers called for removal.

The Secret Serice has urged Trump not to hold any more outdoor rallies in the wake of the shooting, though the former president has refused. Trump recently announced plans to return to Butler for another rally in the near future.

“I WILL CONTINUE TO DO OUTDOOR RALLIES, AND SECRET SERVICE HAS AGREED TO SUBSTANTIALLY STEP UP THEIR OPERATION. THEY ARE VERY CAPABLE OF DOING SO. NO ONE CAN EVER BE ALLOWED TO STOP OR IMPEDE FREE SPEECH OR GATHERING!!!” Trump wrote in a Truth Social post.
